' `In my previous application Serial No. 159,038 tiled April 2.9,.195ObnowYabandoned, for Blade Changer, I have disclosed full details of a razor blade changer and The devices of the present application are similar to those disclosed in the said application, except in the features hereinafter described in detail, and the present specification will be confined to a description of the novel features forming the present invention together with such other features as appear necessary to a full understanding thereof.

In my previous application, Serial No. 54,618, filed October 15, 1948, for Razor and Blade Magazines Therefor, I have also disclosed a razor blade changer and magazine, including a holder for a razor and for new and used blade magazines, together with pusher mechanism for accomplishing a blade change. The present application being concerned with improvements in the blade deilection arrangements for guiding a blade in its passage from the razorinto the used blade magazine and to the adaptation of the magazine therefor. The said application, Serial No. 54,618, has now been issued as Patent No. 2,697,276, granted December 21, 1954,

The magazine casing, as shown in Figures 1 and 2, is formed of a single sheet metal blank. The blank edges 1 and 2 are spaced apart to provide a slot 3, run-- ning the full length of the casing, and adapted to accommodate a pusher or blade ejector element. Side walls 4 and 5 and bottom wall 6 cooperate to form a generally rectangular sleeve, the ends of which are closed by the end walls 7 and 8. End wall 7 is notched under the slot 3 to accommodate the pusher and end wall 8 is spaced from the top and bottom walls to provide slots for ejecting new blades and receiving used blades. The

United States Parent() "ice 2 top walloverhangs the end wall 8 at 9 and 10 to guide a blade being ejected from the magazine and the bottom wall 6 overhangs the end wall 8 to guide a used `blade during insertion into the magazine. End walls 7 and 8 have lsections 11 slanted with respect to the side walls and the end walls generally, which slanted sections serve to engage the ends of the cutting edges of the blades for holding a stack of blades in position in the magazine and protecting their cutting edges from contact with the side wall 4. A cutout or aperture 12 is provided in thel wall 6 adjacent the used blade receiving slot, to accommodate a blade guiding lelement as later described. The magazine vof Figures l and 2 is shown in exhausted or used blade receiving condition, vthe blade positioning spring 13 being seated against the upper wall of the' casing for holding a stack of used blades against the bottom wall 6.

As will be apparent the designation of the magazinewalls as upper, lower and side walls is; arbitrary and for convenience of description, as theV magazine may be held and operated in various positions. Figure`3 shows a blade changer plate or frame 20 held in a box,

indicated fragmentarily, with a pair of magazines A and' B and a razor C in position on the plate. Only` the head end and part of-the handle of the razor are shown,"

it being understood that the handle is of usual length.`

A pusher 21 is pivotally and slidably mounted onja bar22 held in brackets 23 struck up out of the plate 20. The pusher has a` tongue 23 adapted Vto enter in the slot 3 of a magazine for ejecting'thetop blade of a stack from the magazine. By pivoting the pusher back asshOWn in Figure 4 the tongue 23 is removed from the magazine slot. Pivoting -the pusher toward the magazine causes the tongue 23 to enter slot 3 in blade ejecting relation to the top blade of a stack within the magazineas shown in Figure 3, in which the pusher 22 is shown in section through slot 33 of Figure 1.

The new blade magazine A is held in position in the blade changer by projections 24 struck up from plate 20 or fastened thereto and by projections` 2S` and 260m a side wall of the magazine. Projection 25 is generallyv parallel to side wall 5 but is oliset to permit it to iit under the plate adjacent a projection 24 in the latter. The arrangements for holding the used blade magazine B are similar but face in the opposite direction.

The new and used blade magazines A and B are identical and interchangeable, apart from the number and position of blades within them. Each time the pusher is operated the top blade 28 of the stack in magazine A will be pushed into the razor C, and will, in turn, push the' used blade 29 from the razor into the used blade magazinev B. The razor is held in proper position for the change by hooks or ledges 30 fitting over its cap and by a clip 31 fitting in an aperture in its back and the guard is pressed up as by the means shown in my aforesaid copending application, so as to release the blade for the change. As soon as the supply 0E blades in magazine A is exhausted, the now iilled used blade magazine B is discarded and the empty magazine A is placed in the used blade position, a new magazine being substituted for the magazine A. Each magazine may thus serve irst for supplying new blades and then for receiving used blades.

The aperture 12 of the used blade magazine B accommodates a deflector 35, which may conveniently be formed by striking up a part of the plate 20 as indicated. This deector extends into the magazine B beyond the inner surface of the Wall 6 for controlling the blade movement during insertion into the magazine. Used blade 29, shown in Figure 3 as partly inserted in the magazine B, is deflected down by deiiector 35, squeezing between the deliector and the top blade of the used blade 3 stack in. the magazine. When the blade 28 hasl been fully inserted in the razor, blade 29 will have been pushed out of the razor and will rest on lip 36. Spring 13 pressing the stack of bladesup toward the center and against deector' 35V toward one end, will tend to rotate the blade 29 clockwise so as to hold its trailing end dbwn on lip 36. Lip 36 will be separated from a blade just startingv to enter the magazine by a clearance necessary to prevent interference but must also hold the trailing end of a blade resting on it in position for engagement by the leading end of the next blade ejected from the razor. Thus it is important that the lip 36 be located accurately within a fraction of the thickness of a blade. As soon as the next succeeding blade has pushed the top blade past lip 36, the top blade will snap down, clearing the way for insertion ofthe succeeding blade.
